<br /> <br />BOWIE RESOURCES LIMITED <br />Bowie No. 1 Mine <br />Reclaimed Coal Mine Waste Bank Inspection - 3rd Quarter 1998 <br />On September 21, 1998, I performed a quarterly visual inspection of the Bowie No. 1 <br />Mine reclaimed coal mine waste bank in accordance with Rule 4.10.2. According to <br />available records, the last quarterly inspection of this reclaimed waste bank was <br />performed by John Menke and signed by Phil Schmidt P.E., on April 1, 1988. <br />I, J. E. Stover, P.E., have a wide variety of experience in the design and construction of <br />earth fill embankments. Nothing was observed during the inspection that would <br />indicate the pile has a potential for failure. The pile and surrounding area were dry. <br />Drainage was adequate. No seeps or spoil springs were noted. The pile has been <br />reclaimed. The pile blends in with the surrounding area so it is difficult to determine the <br />areal extent of the reclaimed waste pile. Records indicate 15" to 24" of non-toxic <br />material was placed over the coal mine waste. The reclaimed pile supports a good <br />stand of vegetation. <br />According to the permit, this waste pile was filled to capacity in August 1983 and <br />reclaimed. In the spring of 1985, spontaneous combustion was detected. Topsoil and <br />cover material were excavated and the hot spot was removed. The area was <br />apparently reclaimed again during the Summer of 1988. <br />The design of the waste disposal area is presented in Volume 6A. To the best of my <br />knowledge and belief, based on my inspection of the pile and previous inspections by <br />professional engineers, the coal mine waste bank has been constructed in accordance <br />with the approved plan. According to the previous inspection, the pile was constructed <br />with 1.5H:1V outslopes. This was visually confirmed during the inspection. <br />The pile is located in a remote area well away from human habitation. A failure of the <br />pile might damage the sediment pond located below the pile. However, a failure of the <br />pile would probably not be a hazard to human life. <br />Recommend maintenance: None ,~~pp0 REG/s~ <br />1 <br />.• <br />i o~~•w~S Sj0' <br />•y~~ <br />' ~' ,~(~~ <br />• f James E.
